Has anyone seen any positive effects from keeping your plants in darkness a few days before harvest? I've heard it help resin production and ripening...
I'm 5 days away and wondering if it'll help.
Thanks

I tryed the 48 hrs dark just before harvest, no visual results. Herb did taste better than other lady that was harvested. So now I just harvest just before light on so all the garbage is in the roots and not being uptaked into buds.

cool ok, I've also heard that thc is at it's peak at night, but not sure if that's acurate either.

The Stichting Institute of medical Marijuana (SIMM), the first company to sell marijuana through the pharmicies of Holland, has been investigating the medical possibilities of cannabis, together with TNO laboritories and the University of Leiden.

One of their discoveries has been that to keep the ripe plants in the dark before harvesting could increase their potency.

SIMM's growers seperated a crop of mature plants, harvested half of them and kept the other half in absolute darkness for 72 hours before cutting and drying.

Analysis of the resulting dried buds showed that some varieties had seen increases of THC of up to 30 %, while the CBD and CBN remained the same.

I heard that keeping the plant in 48 hours darkness tricks it into thinking winter is coming, so it puts all its energy reserves into the buds.

Been doing alot of my own tests with this it definately makes the weed more potent simply because like the earlier post stated they think its winter and they are about to die so it pushes all of its energy to the buds and what makes it even better if your flushing with water (no nutrients) the last week but i will say this the best results i had was 72 hours of darkness i even went as far as 120 hours but the difference wasnt noticable so i would say stick with 72 hours of darkness before harvest just my 2 cents thanks and happy smoking:joint:

With No Water 4 72 hrs?? (I've already deprived them water for 48 hrs, so that would be 120hrs no water!!) Will it be bad 4 the leaves? I want to make hash with the trim and fan leave so i don't want to damage them...

there are little tiny hooks all over the fan leaves, so you dont want to use them in anything you might eat because they can irritate ur intestines. Also, for bubble hash the fan leaves are useless because that hash method involves knocking the trichs off the outside of the vegetation, not extracting disolved thc from the juices of the plant.
While it is not terminalogically correct, i tend to think of leaves without trichs as fan leaves, and if they have trich coverage they are just leaves. The fan leaves are the solar panels, but once they are covered in trichs the ammount of light they can absorb is reduced substantially, so they don't really fullfill that function anymore. Clearly if the leaves are covered in trichs then you can use them in bubble hash :).

Possibly I misunderstood what you were saying due to your phraseology but THC/resin is only found in/on the trichomes so regardless of what method is used hash/THC/resin only comes from trichomes on the leaves that are used and not from any plant "juices." Bubble hash is just another method of removing/collecting THC/resin for production of hash.

thc can be gotten using the butane extraction method from all parts of the plant to a varying degree. I know this is true because i make honey oil out of vegetating leaves/stems and clippings all the time. You just grind up all your clippings and stuff down to a powder and then run butane through it under pressure. This will dissolve the small amount of THC that is present in this material and once you boil off the butane you can strait smoke it, eat it, anything; it is pure resin. You can also smoke stem or trich covered leaves and get high to a varrying degree, it just gives you a mad headache because of all the chlorophyll and nitrogen in those parts of the plant. We smoke sensimilla now, but people used to smoke most of the hemp plant back before we started hardcore breeding THC production into the current day MJ plant.

Bubble hash is knocking trichs off the outside of leaves and bud using cold water generally. If you took all the shit u used for bubble hash, dried it and then ground it up and ran butane through it you would get a little bit of honey oil.

72 hrs darkness is an old hippie fable. plants get energy from the sun, there is no way that taking the energy from a plant can make it do better. and just so you all know, plants are not conscious so they don't "think winter is coming".

So it is; "an old hipple fable" eh?

Why is it that so few people here read an entire thread before tapping away at their keyboard?
